I know that this references an older thread, but on their album Perrenial Favorites (think that was the title - set up like a Depression Era seed catalog), the N. Carolina Southern 20s-30s jazz band Squirrel Nut Zippers had a song called The Kraken. Lyrics would indicate that it's somewhat Cthulhuesque, but musically it's a full-on Weimar Republic German Expressionist Opera exhuberant freak-out. I love those guys. They were doing their bootlegger era Southern thing for years, and then the swing thing hit circa '93 and they got labeled, even though most of their work references/is inspired by much earlier influences. Of course, later they did do some Forties stuff when the money was right, but man, they hated being lumped-in with the rest of the swing crowd. Still, great weird song. Somebody listened to their Kurt Weill before writing this one.
